Insize 3222 Tubular Inside Micrometers

Insize 3222 Tubular Inside Micrometers

The Insize 3222 Tubular Inside Micrometer series is built for measuring large internal diameters across an exceptionally wide range, using a .5" travel micrometer head paired with a set of extension rods. As you move up through the series, from the 2"-6" model to the 2"-60" model, additional extension rods are supplied to reach the larger end of the range, letting one tool cover diameters that would otherwise require several separate micrometers. Each unit features carbide measuring faces for long-lasting durability and comes supplied with setting standards, making it a dependable choice for mechanical engineering, manufacturing, and quality control work where large-bore internal measurement is a regular part of the job. Common applications include checking tubes, cylindrical parts, and other hollow components across automotive, aerospace, and general industrial settings.
